根据此链接得到解决方法：

Solution
Recommendations for protecting against this vulnerability can be found at:
My Oracle Support Note 1340831.1 for Oracle Database deployments that use Oracle Real Application Clusters (RAC).
My Oracle Support Note 1453883.1 for Oracle Database deployments that do not use RAC.

目前这里环境不是RAC，参考文档1453883.1：

Using Class of Secure Transport (COST) to Restrict Instance Registration (文档 ID 1453883.1)

找到两种解决方案：

SOLUTION
There are two methods that can be used to protect the listener using COST "SECURE_REGISTER_listener_name =" in stand alone database installations.
1) Restricting registration to the TCP protocol (Requires the fix for BUG:12880299)
- or - 
2) Restricting registration to the IPC protocol (The patch for BUG:12880299 is NOT required for the IPC method)
Either method accomplishes the same goal but it is your choice which type to implement subject to the restriction* noted below. Both methods will be discussed.
#8226;The second method (using IPC) cannot be used if the database is a member of an Oracle Data Guard broker configuration.

我这里选择第一种解决方案：

1) Restricting registration to the TCP protocol (Requires the fix for BUG:12880299)。

2.应用解决方案

2.1 确定现状

监听配置文件：listener.ora

存放路径：cd %ORACLE_HOME%/network/admin

内容(保证安全，所有IP相关信息已二次处理)：

# listener.ora Network Configuration File: E:oracleproduct10.2.0db_1NETWORKADMINlistener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.138)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:oracleproduct10.2.0db_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ANY")
)
(SID_DESC =
(GLOBAL = orcl)
(ORACLE_HOME = E:oracleproduct10.2.0db_1)
(SID_NAME = orcl)
)
)
ADR_BASE_LISTENER = E:oracle 

数据库监听信息,原始都是空值：

SQLgt; show parameter local_listener
NAME TYPE VALUE
------------------------------------ ----------- ---------------------------
local_listener string
SQLgt; show parameter remote_listener;
NAME TYPE VALUE
------------------------------------ ----------- ---------------------------
remote_listener string
SQLgt; 

2.2 尝试应用解决方案

2.2.1 停止监听

lsnrctl stop listener

2.2.2 修改监听配置文件

Add the COST TCP protocol restriction "SECURE_REGISTER_[listener_name] = (TCP)" to the listener.ora.
Match the COST parameter variable listener_name with the name of the listener you are using in the listener.ora, e.g., If your listener name is "LISTENER_PROD" then use SECURE_REGISTER_LISTENER_PROD = (TCP)

实际修改过程：

切换到监听配置文件所在路径：

cd %ORACLE_HOME%/network/admin

直接修改listener.ora文件，在文件的末尾添加一行：

SECURE_REGISTER_LISTENER = (TCP) 

2.2.3 启动监听

启动监听：

lsnrctl start listener

立即注册动态监听：

SQLgt; alter system register;

2.2.4 设置local_listener

alter system set local_listener='(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.1.138)(PORT = 1521)))' scope = both;
show parameter local_listener 

2.2.5 查看监听服务信息

lsnrctl services listener
E:oracleproduct10.2.0db_1networkADMINgt;lsnrctl services listener
LSNRCTL for 32-bit Windows: Version 10.2.0.3.0 - Production on 21-9月 -2016 10:2

3.验证修补情况

3.1 注释COST规则验证监听情况

3.1.1 注释掉listener.ora文件的COST规则并重启监听

Comment the COST rule in listener.ora and restart the listener.

直接修改listener.ora文件,在之前添加的一行前面加上"#"注释此行。

#SECURE_REGISTER_LISTENER = (TCP) 

重启监听：

lsnrctl stop listener
lsnrctl start listener 

3.1.2 设置remote_listener后查看监听服务信息
